Upcoming SBIR Phase III Kickoff Meeting for Active Gust Load Alleviation Control Wind Tunnel Experiment to be Held November 16

A kick-off meeting for a Small Business Innovation Research (SBIR) Phase III effort will be held at NASA Ames on November 16, 2017. The prime contractor, Scientific Systems Company, Inc. (SSCI), and their subcontractors, Boeing and the University of Washington, will present their project plan to conduct an active Gust Load-Alleviation (GLA) control wind tunnel experiment in Fiscal Year (FY) 2018 at the University of Washington Aeronautical Laboratory (UWAL) in collaboration with NASA Ames. This Phase III effort is an extension of the Phase II effort that includes a real-time adaptive drag-optimization wind tunnel experiment at UWAL in FY 2017. The proposed GLA control wind tunnel experiment will validate the Variable Camber Continuous Trailing Edge Flap (VCCTEF) and multi-objective GLA technologies developed at NASA Ames, as well as the Boeing/SSCI predictive GLA technologies based on Light, Imaging, Detecting, And Ranging (LIDAR) sensors.

BACKGROUND: Modern advanced transport aircraft, such as the Boeing 787 and 777-X, employ light-weight flexible composite wing structures for fuel efficiency. The wing flexibility causes the aircraft to be more susceptible to gust excitation and maneuver loads that can compromise ride qualities and structural integrity. GLA is a flight control technology aimed at reducing the response of an aircraft to gust excitation. Currently, this technology has been certified for commercial transports such as the Boeing 787. The Advanced Air Transport Technologies (AATT) project is conducting research to develop advanced technologies to enable high-aspect ratio wings for future transport aircraft. The VCCTEF technology developed at NASA Ames is a wing-shaping control device that has been studied for its potential applications for future high-aspect ratio wing transports. The AATT project has been conducting research to develop multi-objective flight control technologies for real-time drag optimization, flutter suppression, and GLA. Validation of these technologies is an important step toward technology commercialization.
